7330 GUI Programming Utility

Sigrid Company LLC is pleased to announce version 1.0 of P7330, our new GUI programming utility for the S-COM 7330 repeater controller.

P7330 includes these advanced features and more:

    • Message Builder - Create a messages without looking up controller codes.
    • Macro Editor - Create & manage macros with automatic creation codes and password insertion.
    • Macro Pick List - Shows currently defined macros. Drag & Drop a macro from the list to any macro field.

Bob's Blog #2: 7330 Internal Audio Levels

In Appendix B (Installation), the 7330 User Manual recommends adjusting the three receive audio pots for 1 V peak-to-peak as measured by an oscilloscope at test points TP9 (RX1), TP10 (RX2), and TP11 (RX3).

That specific level is maintained throughout the controller’s audio section. This blog explains why it was chosen.

Bob's Blog #1: 7330 Digitally Stored Speech

Years ago, the S-COM 7K and similar controllers used voice synthesizers to create speech for talking clocks, talking calendars, announcements, and so on. Users could not add their own words to the vocabulary due to the specialized hardware and software involved, so we contracted with a language lab to offer a word creation service. EPROMs were programmed with word files from the lab and shipped to customers for installation in their 7K SSMs (Speech Synthesizer Modules).

7330 Controller Training Slideset Updated

Today I taught a Repeater Controller training class in the Denver area.  In preparation for the class, I updated the slideset that has been posted on the web site since the last time I taught the class in 2014.
 

7330 Speech Library Update Now Available

Yesterday I posted an updated to the 7330 Speech Library, V1.3.  This is an optional update that fixes the mispronunciation of the phrase "http://www.".  It also includes an improved version of the letter "S".  We have received several reports of "S" sounding like "F" in some cases and are making this fixed version of the letter "S" available.  

You can find the updated library file on the 7330 Firmware Upgrade page.

Q: How do I test my custom words on my Windows PC?

When building a custom audio library from individual words or phrases, it's useful to be able to quickly play those words from the raw files stored on your Windows PC instead of going through the entire process of building and downloading a custom audio library to the 7330 only to find it doesn't work.  The way most of us play a custom word on Windows is to run Audacity, import the file, then play it. (See 7330 manual page 23-13.)

Another FAQ added to our examples page

We've just added another example to our FAQs and Programming Page.  This one was submitted by an owner and describes how to get a scheduler setpoint working.

Q: How do I delay the PTT on a port after a power cycle?

After a power failure, some radios require that the PTT not be asserted for some amount of time.  You might need this if you have a tube power amplifier that needs to warm up, a Yaesu DR-1X that might lock up, or a Kenwood TKR-x50 Version 1 that switches modes.

This example uses a User Timer (see page 20-1) that is started by the Power-Up Macro (see page 5-28).  Macros disable the transmitter PTT (see page 11-26), then reenable it after the delay time.

7330 ScriptKit Available

The 7330 Script Kit can be used as a starting point for configuring the ports of a 7330 with various Port Personalities.  I currently have examples posted for a Repeater, a Wired Link (e.g. EchoLink, IRLP, Allstar, another controller) and a Control Receiver.  You can find the Script Kit and its contents here:
 

New 7330 Programming Example: Final ID without CTCSS

This week I was asked how to configure a repeater to ID without a final CTCSS.  This programming example is one way to implement this solution.
